BOMB.

Specification of Letters Patent.

PatentedFeb. 18, 1919.

Application filed January 9, 1918. Serial No, 210,992

To all whom it may concern:

Be it known that I, CHARLES J. Moses, a citizen of the United States ofAmerica, residing at Bogota, in the county of Bergen and State of NewJersey,ha've invented new and useful Improvements in Bombs, of which thefollowing is a specification.

The invention relates to improvements in bomb construction.

Its principal object is to provide a device of this character which maybe dropped from great heights and assured of explosion at the time ofimpact with the earth.

A second object is to provide a device to be exploded by a percussioncap, the latter being set off by the impact of a piston member whichoperates against the retarding efiect of an air-cushion.

A third object constitutes the provision of means attached to the freeend of the piston whereby the bomb, when dropped, will be assured ofimpact with the earth on this means.

A fourth object is to make this means which is attached to the end ofthe piston ofthe device is set forth in detail in the de-" scriptionwhich follows.

In illustrating the invention, it is shown in but one embodiment towhich, however, it is not to be restricted. An actual reduction topractice may suggest certain desirable changes or alterations and thesethe right is claimed to make, in so far as they may be compatible withthe spirit of the subjoined claim.

In the accompanying drawings:

Figure 1 is a perspective view of the invention.

Fig. 2 is the longitudinal sectional view.

Fig. 3 is the transverse sectional view.

Referring to the drawings, 1 is a cylinder which may be made of anysuitable material but which is preferably made of metal. One end of thiscylinder is open but the other end which is the bottom end is closed andis indicated by the numeral 2. Approximately at its longitudinal center,a disk 3 is attached on the interior of the cylinder, being held inplace by rivets or headed pins 4 which pass through the cylindrical wallof the cylinder at uniformly spaced points thereon and enter thecircular edge of the disk This disk 3 carries at its center a percussioncap 5'which is affixed therein in anyfsuitable manner and which isadapted to be contacted with on its bottom enc The open end of thecylinder 1 is closed by a detachable cap 6 having an internally threadedflange, so that ,it may be screwed onto the open end of the cylinder '1which is provided with exterior threads at its top.

At its center the cap 6 has affixed to it, by any suitable means ofattachment, the fantail thumbpiece -8 by means of which the cap 6 isattached to or if detached from the cylinder 1.

The interior space of the cylinder, comprehended between the-disk 3 andthe cap 6, is designed as a compartment for explosive material, such asdynamite, trinitrotoluol, or the like. The percussion ca 5 contacts, atits-upper end,-w-ith this exp osive material, and is designed toignitethe latter when-set off by means yet to be described.

The bottom end 2 of the cylinder is provided with a central bore throughwhich the piston rod 9 slidably passes, this rod receiving on its-upperend, by threaded engagement in the center thereof, the piston 10. Boththe piston -10 and the'closed end 2 of the cylinder are provided withseries of apertures or openings spaced uniformly in circles concentricwith the piston rods, the piston having the apertures 11 and the bottom2 by the apertures 12.

At the lower or free end of the piston rod 9, a disk 13 is attached, therod having its extreme end 141- reduced in diameter and provided withsuitable threads by means of which engagement is eflected with the disk13. This reduction of the diameter in the end 14 results in theformation of a shoulder on the rod 9 and the disk 13 abuts this shoulderwhen secured in position on the rod.

The disk 13 is designed to be of such a diameter as to preclude itsentering the earth when the bomb is dropped from great heights and it isalso to be of such weight that the center of gravity of the device as awhole will be in the vicinity of this disk. With this arrangement thebomb is assured of hitting the ground disk foremost.

The holes ll and 12 in the piston 10 and closed end 2 of the cylinderrespectively are provided for the purpose of allowing the air containedin the bottom portion of the cylinder to be ejected quickly when thepisholes are not such diameter, however, asyto totally remove allevidences offan air-cushion above thecylinder at the time the bomb visdropped on theground; I There is inpressed abovethe piston, so that someresiliencyj m ay be had inthedevice at the time" i that it hitsthe'ground,the airi'contained inthe'Qcylinder issuinglthrough theaperturesv 11 and 12 at the proper rate to permit the i pistonkto movetoward the disk 3 with sufficient force to set ofi the percussion cap 5by'impact therewith. 1 1
